Rietveld refinement results to wyckoff

Rietveld refinement is a technique described by Hugo Rietveld for use in the characterisation of crystalline materials. The neutron and X-ray diffraction of powder samples results in a pattern characterised by reflections (peaks in intensity) at certain positions. The height, width and position of these reflections can be used to determine many aspects of the material's structure. The Rietveld method uses a least squares approach to refine a theoretical line profile until it matc… WebMar 1, 2012 · Results of the Rietveld structural refinement are presented in Table II, and the atomic parameters of Gd 117 Fe 52 Ge 112 are listed in Table III. Values of R p and R wp are 0.099 and 0.128, respectively. The observed and calculated data and the differences of powder diffraction patterns of Gd 117 Fe 52 Ge 112 are shown in Figure 1.
